New Technologies
to Outperform Concrete
RenovAction is Myrtha Pools’ patented and exclusive technology specifically developed for swimming pool refurbishment and renovation of existing pools.
The process is based on Myrtha technology’s pre-engineered modular system, which
incorporates the use of precision-engineered PVC laminated stainless steel panels and
a buttress system. RenovAction solves all of the problems that often arise in concrete,
gunite, or shotcrete pools that have been in operation for extended periods of time.
Why Renovate?
1. Many existing pools fail to meet today’s health code regulations and therefore require
modifications necessary to bring them into compliance.
2. In order to meet new design and engineering criteria, refurbishment is the perfect solution. Older pools can be modernized with numerous additional leisure components
including: free-form sections, lazy rivers, water play equipment and hydro-massage
areas.
3. Outdated filtration equipment and older recirculation technology need to be updated
from a skimmer system to overflow gutter technology.
4. Traditional reinforced concrete, gunite and shotcrete pools will eventually develop structural problems that require significant maintenance and repairs resulting in a substantial
investment of both time and resources.

The Materials
RenovAction uses superior materials that Myrtha Pools has specifically designed for
swimming pool use.
Stainless Steel
PVC
Finishes
High-quality stainless steel guarantees extremely long
life of the structure. RenovAction uses exclusive modular
components eliminating welding of the panels, which
are subject to increased risk of corrosion. Stainless steel
ensures maximum mechanical strength of the individual
panels, guaranteeing the structural integrity of the entire
pool.
Perfect waterproofing is ensured through the unique
process of bonding PVC to the Myrtha steel panel. A
hard PVC membrane is hot-laminated to the steel in
the manufacturing process and reinforced membrane
is used on the floor of the pool in order to ensure
waterproofing.
To achieve high-level finishes, RenovAction uses
ceramic and special vitreous mosaics, as well as
distinctive stone and marbles that complement the
range of PVC colors.
Unlike traditional concrete installations RenovAction
exclusively uses ceramic tiles to cover the upper part
of the pool panels. The superior quality of the adhesive
materials utilized, significanlty limits the occurrence of
traditional problems such as the detachment of the tiles.

public use and more than 50 installations for
international swimming events, Myrtha has
references in over 70 countries worldwide.
Myrtha Pools boasts an advanced technical
department that allows for direct transmission
of the manufacturing drawings to production of
the pool components; a Research & Innovation
team that continually strives to improve on
the Company’s already industry leading
technology; installation personnel trained at the
Company’s Pool Academy; and a Company
incumbent on a complete pool package. All of
these factors ensure that you will have one of
the best products on the market today.
Renovation
Speed
The renovation of a concrete pool
requires an extended period time
for preparation, curing of adhesives,
and drying time for plaster and
waterproofing materials. RenovAction
allows for rapid installation stages
without lengthy pool preparation
times or the use of specialized
building equipment. This avoids any
prolonged pool down time.
Minimum
Interventions,
Zero Demolitions
RenovAction does not require
destructive demolition of the existing
structure, thereby resulting in
considerable savings with regard to
both the installation time and overall
costs. The internal surface of the
original pool remains unchanged and
only the accessories on the walls or
floor will need to be replaced.
Fixed Costs
RenovAction reduces both
refurbishment and routine operating
costs of the pool. Much higher
costs are typically associated
with maintaining traditional pool
finishes as well as regular ongoing
pool maintenance. The speed of
installation also significantly reduces
the risk of cost overruns.

Long Life,
Extensive
Guarantee
Suitable for
Difficult Field
Conditions
RenovAction pools offer a virtually
unlimited lifespan thanks to the
structural integrity of the materials
and advanced technological features
of this modular system. For these
reasons Myrtha can confidently
warranty its RenovAction pools for
many years.
Seismic activities, soil conditions or
dramatic temperature swings will
damage traditional concrete pools.
The RenovAction design and seismic
engineering are flexible and are
therefore the ideal system for pools
built in such conditions. In specialized
and challenging environments, such
as elevated floors of buildings or
in limited spaces, there is minimal
change required to accomodate the
pool dimensions thanks to the ability
to adjust the distances.
Low and Easy
Maintenance
Environmentally
Friendly
Unlike traditional construction,
RenovAction pools do not require a
significant maintenance schedule. The
RenovAction structure is sturdy and
not subject to dimensional variation.
It will not experience cracking or
deterioration of the pool shell and is
not affected by the aggressive action
of chlorinated pool water.
With most governments
recommending the reduction
of CO2 emissions Myrtha Pools
commissioned ACOR Consultants to
calculate the energy used in building
a Myrtha Pool. The carbon footprint of
a Myrtha Pool is significantly lower by
50% compared to a traditional pool
made with concrete and tiles.
What does this mean? The energy
savings of a Myrtha Pool is enough to
provide heat for a 100 sqm house for
at least 45 years!

The Installation Process
The RenovAction installation process is both simple and fast, without the possibility of
mistakes or delays in the renovation work.

4
Rail Installation
Spacer Installation
Panel Installation
The existing surface of the pool is
commonly left untouched. Stainless steel
rails are aligned and affixed to the pool
wall prior to panel installation.
High density foam spacers are installed
between each rail to avoid any bending
of the panel. The spacers allow for a
high degree of installation precision.
They are glued to the concrete wall and
trimmed to panel level with the use of a
high temperature electric cable.
Wall panels are inserted into the prealigned rails. Special corner pieces are
manufactured, which are the starting
point for the RenovAction installation.
Overflow Gutter
Installation
The overflow gutter is installed on steel
supports, which are anchored to the existing
concrete. The gutter is manufactured with
Myrtha stainless steel and is able to be
installed at adjustable heights and with a
transversal sloping angle.

Panel Sealing
Joint Protection
Once installed, the entire structure is
waterproofed with a combination of
semi-rigid PVC profiles and a special
Myrtha sealant, which is applied to the
joints of the wall panels, guaranteeing a
perfect weld on the entire surface.
Reinforced PVC tape is welded to
the gutter joints to ensure additional
waterproofing.
7
Floor Covering with
Reinforced PVC
Membrane
The floor is lined with a special reinforced
PVC membrane. The membrane is
supplied in rolls which are hot welded
together at the seams. The wall panels
and the floor are joined together by a
PVC profile, which is also hot-welded to
the walls and the floor.
8
Finish Installation
Ceramic tiles are applied on the top
of the Myrtha surface for a clean and
elegant finish. Adhesion of tile to a
Myrtha stainless steel surface is much
easier and safer than to a concrete
surface, as there is no possibility of water
penetration beneath the tiled surface.

Individual Solutions
for Every Installation Challenge
Overflow Gutter
Case A
Overflow Gutter
Case B
As per project requirements, the new
gutter section can be positioned by
partial removal of the existing concrete
deck, which creates a recess for the
installation of the Myrtha gutter. This
solution does not obligate changes to
the surrounding pool deck level.
Alternatively, the Myrtha gutter can be
situated directly onto the existing pool
deck without demolition. The surrounding
deck level will need to be raised to the
new overflow level by means of a step
adjacent to the new RenovAction gutter.
The resulting increase in the pool depth
allows for a comprehensive modification
of the water circulation system, as there
is enough space to install pipes and
fittings necessary for floor return inlets.
This solution eliminates the need for
excavation to access the old piping.
The Circulation System
New pipes are embedded in a 20 cm bed of gravel which is covered by a light layer of concrete.
It is then lined with PVC floor membrane to ensure water tightness. This allows for a remarkable
improvement of water circulation in the pool and is a considerable departure from an obsolete
recirculation system with an insufficient number of inlet fittings.
10 | RenovAction
RenovAction_revised.indd 10
21/05/13 15.05
Regulator
In some cases when it is not possible
to eliminate the existing concrete gutter,
RenovAction gives the opportunity to
use a special adjustable steel profile
called "Regulator". The Regulator is
anchored to the existing concrete
wall and allows for adjustment to
the new overflow level. A reinforced
membrane is then welded on this
profile and connected to the old gutter,
to guarantee waterproofing of the
surface. This special solution is cost
effective although the scope of work is
not as comprehensive as in a standard
RenovAction.
Portholes and
Windowed Walls
Staircases and
Recessed Steps
For competition pools originally
equipped with portholes or windowed
walls, RenovAction technology offers
the possibility to maintain the same
accessories in the renovated project.
RenovAction panels are positioned
in the original openings in the
walls. Portholes or windows for the
underwater photography or video are
installed in the panels with a special
flange system.
RenovAction guarantees maximum
flexibility of design with recessed stairs
and built-in steps. Recessed ladders
are built into a RenovAction panel, with
a minimum depth allowance for treads,
then installed in the same manner as all
other panels.
SoftWalk® Floor
The special SoftWalk® foam mat is
permanently adhered to the floor and
covered by PVC membrane. It does not
deform and maintains elasticity through
the years. Combined with the non-slip
floor membrane, it is the ideal solution
for obtaining greater safety in the pool.
SoftWalk® is an excellent choice for multipurpose pools that include activity for
shallow water pools, spray-pads and beach
entries.

21/05/13 15.05
Variations
and Finishes
The RenovAction technology has been developed with the
goal of providing the same range of design solutions and
finish options as are available with new installations. Most
finishes can be applied both on rectangular shapes and on
free-form pools.
Skimmer
The traditional Skimmer
version, which establishes
the water level below deck
level, has a ceramic finish that
enriches the visible part of the
pool and aids with cleaning
operations. This skimmer
system is ideal for public pools
with smaller dimensions.
Overflow Gutter
Classic
The Myrtha Classic Overflow
gutter is ideal for all pools and
guarantees an excellent water
flow. It has reduced dimensions
while still maintaining an
aesthetically uniform mirroring
surface. It is completed with a
simple but smart PVC finish on
the upper part of the panel.
12 | RenovAction
RenovAction_revised.indd 12
21/05/13 15.05
Overflow Gutter
Classic Competition
This structure is ideal for large
competition pools, as the PVC
coping is flush with the wall
panels, either on entire perimeter
of the pool or on the two short
sides only. This technology is
also the most suitable for the
renovation of pools that need to
meet international regulations.
Both the Classic and the Classic
Competion gutter styles are
available with a wide variety of
finishes.
Overflow Gutter
Ceramic 1
For public pools used mainly
for training sessions, the
Myrtha Ceramic 1 is the most
commonly used and appreciated
technology. Its ceramic tile, with
integral finger hold, places the
overflow gutter slightly removed
from the pool wall so the wave
produced by the swimmer is
better absorbed and does not
affect the swimmer’s pace.
Overflow Gutter
Ceramic 2
The Myrtha Ceramic 2 gutter
profile incorporates two ceramic
tiles, one provided with integral
finger hold, that place the overflow
gutter slightly further back from
the pool wall. This guarantees the
maximum absorption of the waves
created during training sessions
and competitive events. This is
the most suitable technology for
competition venues.
RenovAction | 13
RenovAction_revised.indd 13
21/05/13 15.05
Vanishing Edge
Ceramic 1
Overflow Gutter
Structural
The Myrtha Structural Overflow
technology is distinguished by
a ceramic tile that functions
as a structural component of
the wall panels. This structure
guarantees a perfect overflow
level while maintaining an
attractive finish and can be
considered the ideal technology
for public leisure pools with any
design.
The Vanishing Edge Ceramic
1 profile is available with an
infinity edge effect that provides
a perfect solution for sites with
slopes or irregular topography.
Commonly it is utilized on the
side of the pool with a deck
level that is lower than the
water level and is finished
with ceramic tile. The overflow
creates a cascading effect into
the gutter. This technology is
an elegant and efficient solution
for leisure pools, particularly in
condominium or hotel facilities.
Recessed Overflow
Gutter
The Recessed Overflow Gutter finishing solution
is Myrtha’s newest alternative to a standard ABS
grate. Special edge elements, specially designed
for swimming pool use, are fixed to the overflow
gutter and allow for the perfect flow of water while
providing an elegant finish to the pool. A variety
of materials and finishes are available for both the
deck and the edge of the pool, such as marble,
stone, wood and porcelain stoneware. These
materials are highly durable and provide high-tech
performance.
14 | RenovAction
RenovAction_revised.indd 14
21/05/13 15.06
Vanishing Edge
Structural
The Vanishing Edge Structural
technology is an evolution of
the Vanishing Edge Ceramic 1
profile. Structural ceramic tiles
overlay the Myrtha wall panels
in a gentle slope, creating a
cascade effect into the gutter.
Headwalls
To comply with F.I.N.A.
regulations for competition pools
that do not have an overflow
structure on all four sides, a
headwall is required at 30 cm
above the water level. The
Myrtha headwall offers a ceramic
tile finish that guarantees ease of
cleaning while also maintaining
the pool aesthetic.
Combined
Technologies
All of the technologies described above
can be combined to meet specific design
requirements. For example, competition pools
can combine overflow technologies with
headwalls; public and leisure pools combine
skimmer systems with one or more vanishing
edges or headwall systems. Myrtha Pools
offers the work of a specialized technical staff
who continuously search for the best solutions
for the client according to their needs and
surroundings.

Systems, solutions,
accessories
A precise installation is imperative in the construction of competition pools. This is why
RenovAction has been selected and specified by Swimming Federations and Organizing
Committees throughout the world for some of their most important competitions, such
2012 London Olympic Games. For competition swimming pools, the RenovAction system
and accessories have been developed to meet F.I.N.A. regulations for international competitions, without compromising safety or quality.

RenovAction_revised.indd 16
21/05/13 15.06
Bulkhead
The Myrtha Bulkhead is used to define
separate areas within the pool and easily
moves along rails installed on the pool deck
thanks to a patented movement system. The
movement system can be either mechanically
or electrically driven. Anchors for starting
blocks are included and other options such
as a footrest step, handgrips, and floating
lane line anchors are also available.
Floating
Movable Floor
This allows the depth of the pool to
be varied providing multifunctional
use of the pool. The floating structure
is anchored to the floor through a
system of steel cables and an actuating
mechanism outside the pool allows the
cables to be positioned and the movable
floor to be fixed to the desired depth.
Starting Blocks
Virtual Trainer
Myrtha Track-Start blocks are officially
approved by FINA and are now used in
all international competitions. The Track
Start starting blocks allow for an Omega
top to be integrated and are compatible
most timing systems. They have been
utilized in the 2012 Summer Olympics
and the U.S. Olympic Team Trials.
LED strips, installed on the pool floor,
are used to monitor the performance of
swimmers during training sessions. The
system contains a number of preinstalled
training programs and can be operated
easily with a wireless system.
Air Safety Cushion
This reduces the diver’s impact by
producing a uniform mixture of water and
air in the area where the diver enters the
pool. Spargers positioned under the diving
board provide adjustable bubbling volume
and intensity.
Removable Headwalls
This provides pools with overflow gutter on
four sides with a 30 cm headwall as required
by F.I.N.A. regulations. It also serves as an
ideal support for timing touch pads, starting
blocks and floating lane anchors.
Waterpolo Visual
System
Lane Markings
and Targets
This F.I.N.A. approved system employs
LED markings placed in the specific
areas of water-polo match rules inside
and outside the pool and allows athletes,
referees, judges and spectators to more
easily follow the progress of the match.
Ceramic lane markings and targets are
available.

The 8-lane warm-up pool
Perth
The Center has hosted outstanding international sporting
events and has world-class swimming facilities, which
include an outdoor water-polo pool built by Myrtha Pools for
the 8th F.I.N.A. World Championships, in 1998.
In 2007 the Center’s management selected RenovAction for
the refurbishment of two 50 m outdoor pools. As proven from
the results of a comparative study performed on the pools, it
was determined that the maintenance of a concrete pool is
more complex and onerous as compared to that of a Myrtha
pool. The Myrtha pool, built in 1996, had not undergone any
substantial maintenance until 2003. Alternatively, the indoor
concrete tiled 50m pools, after only 9 years of operation,
have since required the total replacement of the ceramic tiles
along with major water-proofing repairs. The renovation of
the pools started in September 2007 and each pool took
only few weeks to finish.

CASE HISTORIES
The 50 m outdoor reinforced concrete tiled pool of the Center was completely renovated
in 2007 using RenovAction technology. For many years the pool had been unusable
due to its deteriorated condition and required major refurbishment. A combination of
RenovAction and Myrtha technology was selected for the complete refurbishment of
the failed concrete pool. The width of the pool was reduced, which would provide area
for the installation of a special needs, barrier free access ramp. Additionally, this solution
provided for an ease of installation for wall inlets circulation system and lighting systems.
The pool is a 50x21x3 m with ceramic overflow gutter on the long sides and ceramic
competition headwalls on the short sides. The completed pool also accomodates 5
sets of recessed steps, barrier free access ramp and mosaic marking lines on the floor.
Phase
Birrong Swim Center, Sydney

Installation of Myrtha components started from the side with the ramp. This side was
completely built with Myrtha Technology and adjusted according to the width of the
ramp. Once the base frame was installed, the new RevovAction panels were affixed
to the existing wall. Upon completion of the panels installation, the overflow channel is
positioned and secured in place. The RenovAction panels were installed directly onto
the walls of the other three sides of the pool.
Vertical spacers were installed between the RenovAction panels and the concrete pool
walls to compensate for any imperfections in the existing structure. Finally, the floor
membrane and mosaic lane markings were applied.

The 25 m indoor pool in Saronno (Northern Italy) was renovated by Myrtha Pools in just
3 months from the time of the project’s approval. The pool, as well as the entire venue,
has been completely refurbished with the ultimate goal of creating a comfortable and
functional structure, with environmentally friendly and energy saving solutions. Construction on the existing pool began first with the leveling of the floor. The existing pool
depth was 4 m but actually was varying from 1.30 to 1.80 m. The number of lanes was
increased from 6 to 8. And finally, the pool was equipped with a blind cover integrated
into the structure. This allows for reduction of heat dispersion and water evaporation
while also protecting the environment from the damage caused by humidity.

CASE HISTORIES
Phase
After a few years of operation, the two reinforced concrete
tiled swimming pools at the Thermal&Spa Fitness Center
of JW Marriott Hotel in Seoul were damaged and required
major refurbishment.
Pools were slightly leaking due to cracks in the original
tiles that allowed water to go behind the tiles. Also the
columns adjacent to the pool had not been properly
waterproofed and increased the issue.
Both pools have been refurbished using RenovAction
technology, with a special Ceramic 3 Overflow gutter.
The main pool (24x12,30x1,20 m) accommodates 4
recessed steps and is provided with SoftWalk mat on the
pool floor, mosaic lane marking and floating lane lines.
The children pool (20x3,70x0,60-1,30 m) has been
refurbished following the original pool design: the
pool’s floor has a double level depth, created by a large
underwater stair that separates the children’s area from
the leisure area. SoftWalk mat has been used for the
floor and steps, and wall hydromassage inlets have been
placed in the leisure area.
